Abstract (en)
[origin: EP2813760A1] The present invention relates to a gas-air mixing device for a combustor, and more specifically to a gas-air mixing device for a combustor which effectively controls the amount of gas and air supplied to a burner provided in a combustor, such as a boiler or a water heater, thus improving the turn-down ratio which leads to increased convenience for using hot water and heat and enhanced durability of the burner. The present invention comprises: a housing, connected on one side to a turbo fan, provided with a space of a predetermined size in the interior thereof so that gas and air can flow therein; a discharge part disposed on one side of the housing and in contact with the turbo fan; first and second air supply parts, provided on the other side of the discharge part and separated by a first partition, for sucking in air from the outside; first gas supply part, divided by a second partition, and a second gas supply part having a protruding part, on the upper part thereof, protruding a predetermined distance, the second gas supply part being formed so as to be equal in height to the protruding part, wherein gas supply by the first and second gas supply parts mixes with air sucked in from the first and second air supply parts and is discharged via the discharge part, and an opening/closing means for blocking the flow of gas and air by closing the second air supply part and the second gas supply part when in low-output mode, and for opening the second air supply part and the second gas supply part so that gas and air can flow when in a high-output mode.
